Equal volumes of 0.10 M Ba(NO₃)₂(aq) and 0.10 M Na₂SO₄(aq) are mixed at room temperature. Which of the following is the correct net ionic equation for the reaction that occurs?
(a) Ba(NO₃)₂(aq) + Na₂SO₄(aq) \rightarrow BaSO₄(s) + 2\,\text{NaNO}_3(aq)
(b) Ba²⁺(aq) + SO₄²⁻(aq) \rightarrow BaSO₄(s)
(c) Ba²⁺(aq) + 2\,\text{NO}_3^{−}(aq) + 2\,\text{Na}^+(aq) + SO₄^{2−}(aq) \rightarrow BaSO₄(s) + 2\,\text{Na}^+(aq) + 2\,\text{NO}_3^{−}(aq)
(d) 2\,\text{Na}^+(aq) + SO₄^{2−}(aq) \rightarrow Na_2SO_4(s)
